Berkeley Lab researchers have revealed how bacteria “steal” genetic information from foreign invaders for use in their own immunological memory system.
Berkeley Lab Researchers Demonstrate First Size-based Chromatography Technique for the Study of Living Cells
Using nanodot technology, Berkeley Lab researchers demonstrated the first size-based form of chromatography for studying the membranes of living cells. This unique physical approach to probing cellular membrane structures reveals critical information that can’t be obtained through conventional microscopy.
Berkeley researchers have answered a central question about Cas9, an enzyme that plays an essential role in the bacterial immune system and is fast becoming a valuable tool for genetic engineering: How is Cas9 able to precisely discriminate between non-self DNA that must be degraded and self DNA that may be almost identical within genomes that are millions to billions of base pairs long.
Through a combination of water, oil and nanoparticle surfactants plus an external field, spherical droplets are being transformed into ellipsoids and other unusual shapes that could find many valuable uses.
